Abstract

The application discloses a measure point device suitable for ground surface settlement of a shallow-buried tunnel and an observation method. The measure point device comprises an embedding portion, a bottom plate substrate, a connecting portion, a vertical ruler substrate and a water level, wherein the embedding portion is used for being embedded into a bed rock from the ground surface; the bottom plate substrate is fixedly connected to the top end of the embedding portion; the connecting portion is detachably connected to the bottom plate substrate; the vertical ruler substrate is provided with an upper surface for placing a vertical ruler and is connected to the connecting portion through a leveling device; and the water level is arranged on the vertical ruler substrate and is matched with the leveling device to work, so that the upper surface of the vertical ruler substrate is maintained horizontal. The precision of the measuring operation can be improved.

Description

technical field [0001] The present disclosure relates to the field of tunnel monitoring and measurement, in particular to a measuring point device and an observation method suitable for surface settlement of shallow buried tunnels. Background technique [0002] The geological conditions of shallow tunnels are generally bedrock. In the observation of surface settlement of shallow tunnels, the common method of laying out measuring points is to drive steel bars into the bedrock, and reinforce them with shotcrete around the bars, and use the top of the bars as a stand. Ruler point. [0003] However, this kind of measuring point still has the following disadvantages in the specific operation process: [0004] First, the stability of steel bars in bedrock is poor, and the measuring points are easily damaged. [0005] Second, when the leveling rod is placed on the steel bar for measurement, because the contact area at the end of the steel bar is small and smooth and inclined, the...
